AKA- Sheldon Cooper is an Alien.
The plot is fairly simple enough; Outcast alien messes up, many times, before helping saving the day and showing the rest of his species that different isn’t always bad.
It’s enjoyable and harmless, but it’s still just a vehicle for Big Bang Theory’s Jim Parsons. While I myself, don’t mind 20 minute boughts of Sheldon, 90 minutes is just a little much.
